Stanford Research SR810 The SR810 Lock-In Amplifier and SR830 Lock-In Amplifier provide
The SR810 Lock-In Amplifier and SR830 Lock-In Amplifier provide high performance at a reasonable cost. The SR830 simultaneously displays the magnitude and phase of a signal, while the SR810 displays magnitude only. Both instruments use digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lock-ins. The SR810 and SR830 provide uncompromised performance with an operating range of 1 mHz to 102 kHz and 100 dB of drift-free dynamic reserve. * 1 mHz to 102.4 kHz frequency range * gt;100 dB dynamic reserve * 5 ppm/ C stability * 0.01 degree phase resolution * Time constants from 10 Micros to 30 ks (up to 24 dB/oct rolloff) * Auto-gain, -phase, -reserve and -offset * Synthesized reference source * GPIB and RS-232 interfacesInput ChannelThe SR810 and SR830 Lock-In Amplifiers have differential inputs with 6 nV/?Hz input noise. The input impedance is 10 M?, and minimum full-scale input voltage sensitivity is 2 nV. The input can also be configured for current measurements with selectable current gains of 106 and 108 V/A. A line filter (50 Hz or 60 Hz) and a 2� line filter (100 Hz or 120 Hz) are provided to eliminate line related interference. However, unlike conventional lock-in amplifiers, no tracking band-pass filter is needed at the input. This filter is used by conventional lock-ins to increase dynamic reserve. UnforRefurbished
